[1] Henriette Hertz is now known mainly through her establishment of the Bibliotheca Hertziana, granted to the Kaiser Wilhelm Institute (KWI) in 1913 (from 1953, the Max Planck Society).
Backed by Ludwig Mond's fortune earned in the British soda industry, the Monds and Hertz maintained an "open house" salon in Rome; regular visitors included Gabriele d'Annunzio, the Italian mathematician Pietro Blaserna, Paul Deussen, the writer Olga von Gerstfeldt and the art historian Ernst Steinmann, Wolfgang Helbig, Theodor Mommsen, Giovanni Morelli, and the violinist Teresina Tua, a/k/a Teresa Tua.
During the ensuing years (1904–1912), Hertz collected the core of a research library focussed upon the art of Italy, and particularly of Rome.
The Bibliotheca hosted the tenth International Congress of Art History of 1912,[5] which featured a plenary paper presented by Aby Warburg.
